Abstract: 644,319. Axial-flow compressors. FAIRWEATHER, H. G. C. (Kaiser Fleetwings, Inc.). April 24, 1948, No. 15285/47. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 11, 1947.] Drawings to Specification. [Class 110(i)] The blade angles vary from root to tip so that the energy imparted to each unit of gas is constant from root to tip. The gas enters the entrance stator and leaves the exit stator of each stage in an axial direction, and the pressure at the exit of the exit stator is constant from root to tip. The circumferential velocity, at a given radius, at the exit of the entrance stator may be kept equal or proportional to that at the entrance to the exit stator. The entrance stator of each stage is a part of or is contiguous with the exit stator of the preceding stage. The rotor and stator blades are preferably made of thin sheet metal of uniform thickness, but the rotor blades may be made of greater thickness at the middle. The theoretical considerations underlying the invention are set. forth in detail in the Specification.

Title: Improvements relating to the detection of the presence of submarine vessels and other conducting bodies
IPC: G01V3/04
Filed: 1918-09-20
Abstract: 188,676. Ionides, A. G. Sept. 20, 1918. Signalling proximity of vessels.-Apparatus for detecting conducting bodies in an electrolyte, and especially for detecting the presence and position of submerged submarines, comprises a pair of immersed electrodes connected to a galvanometer which is ducted by a direct current given out by the submarine. As shown in Fig. 1, the two electrodes A, B, spaced apart, are towed by or attached to a searching vessel C carrying the galvanometer D, which is deflected when the electrodes pass over or near a submarine. If the submerged body does not give. sufficient current, the body may be charged after the manner of a secondary battery, by direct current sent cut by electrodes E, F which are also towed by the vessel C and are situated ahead and astern of the detecting-electrodes A, B as shown in Fig. 2. The charging-current supplied by the source G is interrupted at intervals, to enable the secondary current sent out by the submerged body to be detected. To prevent inductive effects owing to the towed cables cutting across the earth's magnetic field they are twinned between the vessel C and the nearer electrode A; and similar effects due to rolling of the vessel are neutralized by a compensating coil. The tow-cables may be of the same density as sea-water or may be buoyed or guided by planes fised to the cables. The detecting-electrodes A, B, may be of wire strands insulated by fibrous material which holds in place a de-polarizing reagent. They may be formed as discs at one end of insulating tubes, and may be surrounded, or covered by a layer of jelly. The charging-electrodes may comprise insulating rods with separated longitudinal flutings lined with metal. The apparatus shown in Fig. 1, may be duplicated, both sets being towed by the same vessel C, and separated transversely to the course by means of kites. The electrodes may be oonnected to separate galvanometers, or to a single differential galvanometer, which will then indicate on which side of the course the submarine is situated.

Abstract: 1480193 Measuring moisture SAINTGOBAIN INDUSTRIES 16 April 1975 [19 April 1974] 15688/75 Heading G1N [Also in Divisions H2 and H5] A window pane 1 for a motor vehicle is provided on its internal face with a network 2 of electrically resistive strips printed on to the pane, and with a humidity detector Ha having two terminals one of which is connected to the network. Preferably the detector has a pair of inter-digitated electrodes of which one connects to a tab 2a formed on the uppermost resistance strip of the network. The detector forms with a resistance 23 a voltage divider for the signal generated by a multivibrator 11. The presence of moisture on the pane reduces the voltage supplied to the diode 15 whereby transistor 17 is blocked. Thus transistor 18 is enabled to act via the relay S to supply current to the network for heating the pane. In an alternative embodiment Fig. 2 (not shown) two humidity detectors are provided (Ha, Hb) coupled to the control circuit through respective capacitors (21a, b). The heater element may be energized in response to a bi-metallic strip (T) when the passenger compartment temperature is so low that there is a risk either of frost on the detector or of ice on the external face of the pane.
